and exact description of the invention, such as-will enable others skilled in the art to which it appertains to. make and use the same.

Our invention relates to improvements in automatic acetylenegas generators, and more particularly to themeans for automatically supplying the feed-water to the carbid in the generator-chamber; and the object 'is to simplify and improve the construction and provide a'positive supply of water to the carbid, so that the generation of the gas will be directly and positively controlled by the amount of gas consumed, so that the generation will be in direct proportiomto the consumption.

To this end the invention consists in the construction, combination, and arrangement of the several elements of the apparatus, as will be hereinafter more fully described, and particularly pointed out in the claim.

In the accompanying drawings the same reference characters indicate the same parts of the machine.

Figure 1 is a perspective view of our improved automatic acetylene-gas generator. Fig. 2 is a vertical section.- Fig. 3 is a horiwlontal section through the feed-Watertank.

1 denotes the generator-tank or'carbidchamber, 2 the gas-holder tank, and 3 the gas holder or bell.

4 denotes the gas-pipe leading from the carbid-chamber to the gas-holder, and it is provided with a plug-cock 5, the stern 6 of which is formed with a horizontal arm 7, terminat-" ing in a top 9 of the; carbid-char'nber 1, so arranged that when it becomes necessary to recharge the carbid-chamber the arm 7 must be turned .to 0ne:side and close the cock 5, thus shu t-' ting off all communication between the gen-' erator and the holder before the cover 9 can be removed from the generator.

10 denotes the water-supply pipe for the p generator, which terminates in a funnel 12.

handle 8, which extends across the Y 13 denotes the Water-supply tank, which is supported by the tank 2, and in it is horizontally mounted a tubular shaft 14 in suitable brackets 15 15. The inner end of this tubular shaft terminates in alateral pipe 16, the end of which isopen and extends through a float 17, secured thereon. The opposite end of said tubular shaft extends through a packneck or nozzle 19, which opens immediately above the feed-.water funnel .12. A bracketlug-box 18 and terminates in a lateral goose-,

20 is fixed to thenozzle 19, and it is provided with a wrist-pin 21, which is encompassed by the lowerend of a rod 22, the upper end of which is pivoted to the lower end of avertical bar 23, having'a vertical sliding engagement with the guide-brackets 21 21, alined on the outside of the feed-water tank. The upper end of this bar-23 terminates in a stirrup 25, which projects into the arm '26, fixed to the top of thegas-holdcf3:

The construction and arrangementare suchthat when not. 'nterfered with the 'float 17 rests upon the surface of the Water in the tank .13, so that the open end of the pipe 16 is above the water-level. lowers (due to the consumption of gas) and the arm 26 depresses the rods 22 23, gooseneck 19, and tube 16-, the float 17 will also be carried down and the open end of the tube 16 submerged, so that the water in the tank 13 will flow through the tubes 16, 14, and 19 into' the funnel 12, whence it passes through the is discharged uponthe carbid,

pipe 10 and path of a horizontal If, however, the gas-bell causing a generation of-gas in the generatorchamber, and this fresh supply of gas passing through the pipe 4 into the tank 2 causes the gas-holder 3 to rise. The upward movement of the which releases the bars 23 22, and the buoyanoy of the float raises the open end of the tube 16 above the water-level in the feed-water tank. Consequently the supply of water tothe carhid is cutoff and the generation ofthe gas is stoppeduntil the holder again falls,

with a like result as in the first instance.

it will of course be understood that various changes in the form, proportion,and the minor details of construction may be resorted'to,

without departing from the principle or sacrificing any of the advantages of this invention.

holder carries with it the arm 26, Y

Having thus fully described our invention, Whitll we claim as new and useful, and-desire to secure by Letters Patentof the United States, is v In an acetylene-gas apparatus, the combination with the generator and the holder communicatin g therewith, a feed-water-inlet pipe for the generator, and a feed water tank mounted above the generator, of a disehargepipe mounted in the feed-water tank and havin'g its outlet end arranged vertically above the mouth of the feed-water-inlet pipe for the generator, 21 float carried by the inlet end of the discharge-pipe, a bracket orarm carried by thegas-holder and projecting into the path of the outlet end of said discharge-pipe, substantially as and for the purpose set forth.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
